apf_portal/docs/development.md

Development guide

This document is the day-to-day reference for working on apf_portal. It covers the repo layout, the prerequisites, the initial setup from a fresh clone, and the commands you'll run during a typical development cycle. It is meant to grow — add sections as the team's workflow does.

For decision rationale, see the ADRs. For onboarding the local environment (terminal, Node, pnpm), see setup/.

The conventions that govern this layout are recorded in:

• ADR-0002 — Nx workspace shape
• ADR-0003 — naming convention (portal-shell, portal-bff, feature-<name>, shared-<scope>)
• ADR-0007 — local hooks
• ADR-0015 — CI/CD shape

2. Prerequisites

A working dev machine for apf_portal needs:

Tool	Why	How
WSL 2 + Debian (Windows) or Linux/macOS native	All commands assume a POSIX shell	see setup/01
Node.js 24 (latest LTS)	Runtime, pinned in .nvmrc	nvm install 24 && nvm use (see setup/02)
pnpm 10+	Mandatory package manager (no npm/yarn lockfile)	corepack enable && corepack prepare pnpm@latest --activate
Git ≥ 2.40	Husky 9 + signed commits eventually	usually default
mkcert	Local HTTPS for cookie-prefix __Host- (ADR-0009)	apt install mkcert then mkcert -install
Trivy (optional, locally)	Dep vuln scan when running ci:scan locally; CI uses an action	apt install trivy or trivy install docs
gitleaks (optional, locally)	Same pattern; CI uses an action	apt install gitleaks or gitleaks install docs
Docker	For Postgres + Redis containers in dev (until on-prem infra ADR lands)	Docker Desktop on Windows, Docker Engine on Linux

Work inside the WSL filesystem (~/Works/...), never /mnt/c/... — the latter has severe I/O penalties that break Nx caching.

---

3. Initial setup from a fresh clone

git clone gitea@git.unespace.com:julien/apf_portal.git
cd apf_portal

# Install deps (also runs `husky` to wire git hooks)
pnpm install

# Generate the Prisma client (until you set up the DB it errors on
# missing DATABASE_URL — that's expected; the generation only reads
# the schema, not the DB).
cd apps/portal-bff && pnpm exec prisma generate && cd ../..

# Sanity check
pnpm nx run-many -t lint test build

For the BFF to actually run end-to-end, you'll also need:

# .env from .env.example, then fill in DATABASE_URL with your local Postgres
cp apps/portal-bff/.env.example apps/portal-bff/.env

# Local Postgres via Docker (one-liner; will be replaced by a Docker Compose file in a later doc)
docker run -d --name apf-postgres -p 5432:5432 \
  -e POSTGRES_USER=portal -e POSTGRES_PASSWORD=portal -e POSTGRES_DB=portal_dev \
  postgres:17-alpine

A proper local-dev infra spec (Postgres HA-like, Redis, OTel collector) will land with the on-prem infrastructure ADR; in the meantime the one-liner above is sufficient to run the BFF.

---

4. Daily commands

Run the apps

pnpm nx serve portal-shell        # http://localhost:4200 (Angular dev server)
pnpm nx serve portal-bff          # http://localhost:3000/api (NestJS)

Both can run in parallel in two terminals; the SPA proxies API calls to the BFF in dev.

Test

pnpm nx test portal-shell         # Vitest (single run; --configuration=watch for watch mode)
pnpm nx test portal-bff           # Jest

pnpm nx run-many -t test          # all projects
pnpm nx affected -t test          # only projects affected since main

Run a single Vitest file:

pnpm nx test portal-shell --testFile=src/app/app.spec.ts

Lint, type-check, format

pnpm nx lint portal-shell             # one project
pnpm nx run-many -t lint              # all projects
pnpm nx affected -t lint              # affected only
pnpm nx affected -t lint --fix        # auto-fix where possible

pnpm nx affected -t type-check        # explicit type-check (independent of test/build)

pnpm nx format:write                  # apply Prettier
pnpm nx format:check                  # CI-style verification

Build

pnpm nx build portal-shell                                   # development build
pnpm nx build portal-shell --configuration=production        # production build
pnpm nx run-many -t build
pnpm nx affected -t build

Generate

# Component in portal-shell
pnpm nx g @nx/angular:component <name> --project=portal-shell --standalone

# Service / controller / module in portal-bff
pnpm nx g @nx/nest:service <name> --project=portal-bff
pnpm nx g @nx/nest:controller <name> --project=portal-bff

# New shared lib (TS-only, consumable by both apps)
pnpm nx g @nx/js:library --name=shared-<scope> --directory=libs/shared/<scope> \
  --bundler=tsc --unitTestRunner=vitest \
  --tags="scope:shared,type:shared" --no-interactive

# New Angular feature lib (front-only)
pnpm nx g @nx/angular:library --name=feature-<name> --directory=libs/feature/<name> \
  --standalone=true --unitTestRunner=vitest-analog \
  --tags="scope:portal-shell,type:feature" --no-interactive

Sweep generated files for process.env.X (dot notation) → process.env['X'] (bracket notation), required by the strict-TS option noPropertyAccessFromIndexSignature: true. The Nx generators don't emit bracket form.

Prisma

# Regenerate the typed client after schema changes
cd apps/portal-bff && pnpm exec prisma generate && cd ../..

# Create and apply a migration in dev
cd apps/portal-bff && pnpm exec prisma migrate dev --name <migration-name> && cd ../..

# Deploy migrations in prod (run by deploy pipeline, not locally)
cd apps/portal-bff && pnpm exec prisma migrate deploy && cd ../..

# Inspect the dev DB
cd apps/portal-bff && pnpm exec prisma studio && cd ../..

CI scripts (runnable locally)

Mirror what the CI does on every PR:

pnpm ci:check      # nx affected -t format:check lint test build
pnpm ci:audit      # pnpm audit --audit-level=moderate
pnpm ci:commits    # commitlint on the PR commit range (uses $COMMIT_LINT_FROM, defaults to origin/main)
pnpm ci:perf       # production build + Lighthouse CI against the static-served bundle

ci:scan (Trivy + gitleaks) is currently invoked from CI YAML rather than as a pnpm script — those tools are Go binaries without clean npm wrappers. Run them locally if you've installed the binaries.

5. Conventional commit cycle

1. Branch from main with a short slug:

   git switch -c feat/portal-shell/auth-login   # or fix/..., chore/..., docs/...
   

2. Commit using Conventional Commits. The local commit-msg hook (commitlint) rejects anything else.

   feat(portal-shell): add login flow stub
   fix(portal-bff): correct env var bracket access
   chore: bump @nx/* to 22.7.2
   docs(decisions): add ADR-0018 for security baseline
   

   pre-commit runs lint-staged → Prettier on staged files. Lint and tests stay in CI.

3. Push and open a PR against main. The CI runs:

   • check (lint, type-check, test, build on affected)
   • scan (audit, Trivy, gitleaks)
   • commits (commitlint on the PR commit range)
   • perf (Lighthouse on the production bundle)
   • a11y (axe-core; placeholder until first real screens)

   All five must be green to merge. PR title must itself be a Conventional Commits message — it becomes the squash-merge subject (ADR-0015).

4. Squash-merge into main. Branch is auto-deleted. Linear history maintained.

5. To cut a release: tag vX.Y.Z on main. The release.yml workflow will pick it up (currently a stub; populated alongside the on-prem deploy ADR).

6. Where to look

Question	Doc
Project rules and the why behind them	CLAUDE.md
All ADRs (decisions index)	docs/decisions/README.md
Initial environment setup (Zsh, Node, pnpm)	docs/setup/
RSSI briefing for ASVS / HDS / etc.	notes/asvs-level-decision-briefing-rssi.md (gitignored, personal)
The dev-team rationale for the UI stack	notes/argumentaire-stack-ui-spartan-cdk-tailwind.md (gitignored, personal)

7. To be added

This doc is intentionally not exhaustive on day one. Sections that will land as the project grows:

• Local infra recipe — Docker Compose for Postgres + Redis + (later) OTel Collector.
• Auth dev-loop — once the Microsoft 365 Developer tenant is provisioned, the workflow for testing OIDC locally.
• Component patterns — the in-house spartan-style components (CDK + Tailwind) as they ship, with a11y notes per component.
• Debugging tips — Angular DevTools, NestJS inspector, Prisma query log, OTel trace inspection.
• Release workflow — once the on-prem deploy ADR lands.
• Renovate / dep update policy — when Renovate is configured.
